MOBILE, Alabama -- The 18-year-old freshman who was shot and killed by a University of South Alabama police officer Saturday morning was apparently on LSD, according to Mobile County Sheriff Sam Cochran.

According to Cochran, witnesses have submitted sworn statements that say they and Gil Collar, 18, were at the BayFest Music Festival Friday night where they ingested the hallucinogenic.

When they went back to the university dorms, Collar allegedly took all his clothes off before he "approached and assaulted people in two vehicles," Cochran said.

"He [Collar] had grabbed her [one of the victims] arm and was trying to bite her on the arm and making weird noises and statements towards this victim," Cochran said.

Just minutes later, surveillance cameras caught Collar, drenched in sweat, trying unsuccessfully to get into the USA Police Department. Less than a minute later, deputies say he began "very actively beating this window glass," in an apparent attempt to break through it.

Shortly after that, USA police officer Trevis Austin, 27, came out of the station with his gun drawn, a move which Cochran said made sense in the situation.

Surveillance footage showed Collar repeatedly lunging at the ground and the officer while alternating through fighting stances as Austin attempted to retreat, according to Cochran.

Although the surveillance footage and witness statements given to sheriff's deputies may point toward a lawful use of force on Austin's behalf, Cochran stressed that the investigation is ongoing.

"We have not reached any conclusions," Cochran said. "We will ultimately present this information to the district attorney, and the district attorney of course will take further actions with, I guess, the grand jury. It's her call."
